Chromatic Dispersion Analyzer 13
3 Setting Up Your Chromatic
Dispersion Analyzer
The parameters you set will be kept in memory after turning off the
FTB-400 Universal Test System.
Setting the Wavelength Range
You can set the wavelength range within which you want to perform your
acquisitions. You can work with predefined bands (C, L or C+L) or set the
wavelength range by using the custom option. This option could be useful
to perform acquisitions in a specific area of a band or between two bands.
To select a predefined wavelength range:
On the Parameters tab, use the Range dial.
To set the wavelength range using the custom option:
1. On the Parameters tab, set the Range dial to Custom.
2. Enter your values in the From: and To: fields. The values you enter
must be between 1530 and 1625 nm, which are, respectively, the lower
limit of the C band and the upper limit of the L band.
IMPORTANT
Make sure you connect the source corresponding to the wavelength
range you select at the other end of the link.
